Abstract
Encysted metacercaniae of Zoögonus are reported from the seaurchin, Psammechinus miliaris, at Wimereux, France. Comparison with descriptions of other larval Stages found at Roscoff and Marseilles indicates that all belong to the same species. Attempts to infect sea-urchins at Woods Hole with the American form of Zoögonus were only partially successful. Bionomic and morphological differences between the European and American representatives of Zoögonus are discussed. It appears probable that they belong to different species.Keywords
